The wire that ejects brass from the LNL gets in the way of dies other than Hornady. To use other dies you will need to either remove the wire and pull the finished rounds off manually or reshape the outside of the mouth of the die for clearance.

I am currrently using a Hornady die, but previously used an RCBS and did the manual thing with no particular loss of speed in reloading, just had to put up with an additional motion.
